What is the Multi-Cartridge Stainless Steel Gas Filter Housing mainly used for?
This stainless steel gas filter housing is designed for high-purity and sterile gas filtration where larger flow capacity or multiple filter cartridges are required. Typical applications include biopharmaceutical fermentation air, pharmaceutical clean gases, electronic specialty gases, food and beverage process gases, and chemical reaction or protective gases.
What types of filter cartridges can be installed in this gas filter housing?
The housing can be configured for different gas filtration media, including PTFE, glass fiber, and stainless steel filter cartridges. Listed cartridge connections include 222, 226, and DOE configurations. Final cartridge selection should consider gas type, required filtration accuracy, operating temperature, flow rate, and sterilization or cleanliness requirements.
How do I choose the correct number of cartridges for my gas filtration system?
The required cartridge quantity depends mainly on gas flow rate, allowable pressure drop, required retention level, operating pressure, cartridge length, and process conditions. Multi-cartridge configurations can provide greater filtration area for higher-flow applications. Providing the required gas flow, pressure, temperature, and filtration objective is the most reliable way to determine the appropriate housing size.
How should I choose between SUS304 and SUS316L stainless steel housing materials?
Material selection depends on gas composition, moisture level, process environment, cleaning or sterilization conditions, and corrosion requirements. SUS304 is suitable for many general gas filtration applications, while SUS316L is commonly selected for pharmaceutical, bioprocess, high-purity, or more demanding environments. Final material compatibility should be confirmed against the actual process conditions.
What operating limits should be considered for this gas filter housing?
The listed maximum operating temperature is 150°C, and the maximum differential pressure is 8 bar. Actual allowable conditions also depend on housing material, seal type, cartridge construction, inlet/outlet connection, and process gas. Temperature and pressure should therefore be evaluated together when confirming the final configuration.
How do I confirm whether this gas filter housing can be integrated into my existing system?
Integration should be checked according to required gas flow, inlet/outlet size, connection standard, cartridge quantity and length, seal material, pipeline pressure, and available installation space. Flange, Tri-Clamp, and threaded connection options are available. Providing your existing pipeline dimensions and gas operating conditions is the most reliable way to confirm compatibility.
